WILLIAM HATCH SMILEY, OF NILES, OHIO.

PRINTING-PRESS.

atented March 5, 1907.

Original application filed March 7, 1905, Serial No. 248,821. Dividedand this application filed December 5, 1906. Serial Be it known that I,WILLIAM HATCH SMILEY, of Niles, in the county of Trumbull and State ofOhio, have invented certain. new and useful Improvements in Printing-Presses, and I do hereby declare the following to be a full, clear, andexact description of the invention, such as will enable others skilledin the art to which it appertains to make and use the same.

The primary object of this inventionis to insure a firm imprint of thetype and to secure great force on the impression for the purpose ofembossing and to compensate for the delays between the imprints whilestock is being positioned and ink is being applied to the type.

The invention will be hereinafter fully set forth, and particularlypointed out in the claims.

In the accompanying drawings, Figure 1 is a view in perspective of aportion of a press equipped with my improvements. Fig. 2 is a side viewthereof with parts omitted. Fig. 3 is a central longitudinal sectionalview. Fig. 4 is a view in perspective of the gearing. Fig. 5 is adetached view of the platen and its support.

This invention is primarily designed for use in connection with abed-and-platen press of the character shown by Letters Patent of theUnited States No. 778,338, issued to me December 7, 1904, a furtherexemplification of which is embodied in my pending application, SerialNo. 248,821, filed March 7, 1905. In the press to' which I refer thestock is fed over a stationary platen by endless conveyers, the travelwhereof is periodically arrested while the stock is inposition on theplaten to receive the imprint or embossing, after the completion ofwhich the stock resumesits travel with the conveyer, from which it islater automatically released. Inasmuch as the means for feeding andpositioning the stock has no necessary correlation to the subject-matterof the present invention, I have neither shown nor described theconveyer nor any of its adjuncts.

Referring to the drawings', 1 designates a stationary frame, and 2 acarrier movable back and forth on inclined guideways 3 of frame 1. Thesides of the carrier are in line with the sides of the frame, and at itslower is movable toward and away from the stationary platen 5. Theplaten consists of a solid bed and a removable frame of rectangularformation, which frame rests upon stops 6 and is secured at its upperend by pivoted hooks 7, engaging posts 8 thereof. The frame is muchlighter in weight than the bed and is designed to bear evenly againstthe latter at every point. By this means I am enabled to readily removea portion of the platenfor convenience in the preparation of make ready.To replace the frame, it is only necessary to position it on stops 6 andto throw hooks 7 into rengagement with posts 8.

The sides of the type-bed carrier 2 at their upper ends are formed withbearings for a cross-shaft 9, which shaft at its ends has crank-pins 10,whereon are fitted the ends of links 12. These links at their lowerforward ends engage cams mounted on shaft 13, having its bearings inframe 1. Through this connection the type-bed is given its reciprocationby the revolution of its shaft 9, and in each downward movement thetype-bed will be brought sufficiently close to the platen to secure afirm imprint. An ordinary throwoff lever 14 is shown as connected to oneof the cams on shaft 13. (See Fig. 1.)

The reciprocation of the type-bed carrier is effected by an ellipticalgear-wheel 15, keyed on shaft 9 and meshing with an eccentricgear-pinion 16, whose short shaft 17is supported by cranked arms 18,(see Fig. 4,) secured at their upper ends to shaft 9 and at their lowerends loosely mounted on a main operating-shaft 19, which latter carriesthe ffy-wheel 20. (Shown in dotted lines, Fig. 2.) On the short shaft 17is a gear-wheel 21, concentric to such shaft and which meshes with apinion 22, fast on f shaft 19. The revolution of shaft 19 iscommunicated through pinion 22 to gear-wheel 21, and thus to shaft 17and through the eccentric gearpinion 16 and elliptical gear-wheel 15 toshaftQ of the type-bed carrier.

By means of the elliptical and eccentric gears I am enabled to insure afirm imprint of the type and secure great force on the impression, andthereby squarely emboss the type on the stock, obtaining also dwells inthe movements of the type-bed carrier not only atthe time of theimprint, but also when the forward end it carries the type-bed 4, whichi type-bed is at the limit of its outward move- ICO ment, during whichthe inlring of the type is effected and fresh stock is positioned on theplaten. By means of this construction an accelerated motion is obtainedbetween the extremes of movement, thereby enabling me to secure rapidoperation of the press, the time consumed in the dwells being more thancompensated by the rapidity of motion imparted to the type-bed. I haveneither shown nor described the means for actuating the ink-fountainor'for inling the type, since it is manifest that any suitablearrangement may be employed for this purpose.

Although my present invention is primarily designed foi use inconnection with printingpresses of the type embodied in my beforenotedpatent and application for patent, yet it is manifest that its use isnot restricted, that it is applicable to any press wherein as betweenthe platen and the type-bed in a printing-press an accelerated anddifferential motion is desired.

I claim as my invention* 1. A printing-press having a platen and atype-bed, one being movable relatively to the other, and means foroperating the movable member comprising an elliptical gear and aneccentric gear intermeshing with` each other for imparting to themovable member a dwell at the extremes of travel and for acceleratingits speedbetween such dwells.

2. In a printing-press having a movable bed, means for reciprocating thelatter and imparting increased force to the imprints, comprising anelliptical gear-wheel and an eccentric gear-wheel intermeshing with eachother.

3. A printing-press having a stationary platen, a movable type-carryingbed, and means for reciprocating the latter comprising shaft,apower-shaft, and an eccentricallymounted gear-wheel driven thereby andmeshing with said elliptical gear.

5. A printing-press having a stationary frame, a type-bed carrierslidably mounted on said frame, a driven shaft mounted on p said carrierand having an elliptical gear, means connecting said shaft and the framefor imparting a reciprocatory movement to the carrier by the revolutionof its shaft, a power-shaft, and an eccentrically-mounted gear-wheeldriven thereby an d meshing with said elliptical gear.

6. A printingepress having a stationary' frame, a type-bed carrierslidably mounted on said frame, a driven shaft mounted .on said. carrierand having crank-pins at its ends, links connected to said crank-pinsand to said frame, an elliptical gear on said shaft, a power-shaft, aneccentrically-mounted gear-wheel meshing with said elliptical gear, ashort shaft for such eccentric gear, a gearwheel on said short shaft,and a pinion on said power-shaft meshing with said latter gear-wheel.

In testimony whereof I have signed this specification in the presence oftwo subscribing witnesses.

WILLIAM HATCH SMILEY.
